[PDF] Acute sleep deprivation increases portion size and affects food choice in young men | Semantic Scholar (2024)

In the largest, most diverse healthy sample of adults studied to date under controlled laboratory conditions, sleep restriction promoted weight gain and positive energy balance, particularly in men and African Americans.

First evidence of phenotypic trait-like stability and differential vulnerability of energy balance responses to two commonly experienced types of sleep loss is found: the findings open the door for biomarker discovery and countermeasure development to predict and mitigate this critical health-related vulnerability.

The present study observed increased hunger, food cravings, food reward, and portion sizes of food after a night of modest sleep curtailment that could lead to higher energy intake and, ultimately, weight gain.

People experiencing reduced alertness after modest sleep loss may be more willing to eat food they recognize as less healthful, and appear to prefer more calorically dense foods.

Though data indicated that students, on average, consumed less fruit and vegetables and more sweets and starches on sleep-deprived days, variance across the population was high, indicating the need for a larger sample population to accurately assess variable relationships.

It is suggested that sleep restriction could be a factor that promotes obesity and, to a lesser extent, estimated physical activity-related energy expenditure in healthy men.

The data show that a reduction in sleep increases energy and fat intakes, which may explain the associations observed between sleep and obesity.

The findings show that one night of sleep deprivation acutely reduces energy expenditure in healthy men, which suggests that sleep contributes to the acute regulation of daytime energy expenditures in humans.

The amount of human sleep contributes to the maintenance of fat-free body mass at times of decreased energy intake and Lack of sufficient sleep may compromise the efficacy of typical dietary interventions for weight loss and related metabolic risk reduction.

Recurrent bedtime restriction can modify the amount, composition, and distribution of human food intake, and sleeping short hours in an obesity-promoting environment may facilitate the excessive consumption of energy from snacks but not meals.

Feelings of hunger as well as plasma ghrelin levels are already elevated after one night of SD, whereas morning serum leptin concentrations remain unaffected, providing further evidence for a disturbing influence of sleep loss on endocrine regulation of energy homeostasis, which on the long run may result in weight gain and obesity.

Short-term sleep deprivation increased energy intake and led to a net weight gain in women and the effect of sleep restriction on energy expenditure needs to be specifically addressed in future studies using reference methods for total energy expenditure.

The data suggest that, in the context of negative energy balance, short sleep does not lead to a state of increased insulin resistance, but may predispose to overeating via separate mechanisms in men and women.

The findings of this study link restricted sleep and susceptibility to food stimuli and are consistent with the notion that reduced sleep may lead to greater propensity to overeat.

In this study, 12 young, healthy, normal-weight men exhibited reductions in the satiety hormone leptin, increases in the hunger hormone ghrelin, and increases in hunger after 2 nights of only 4 hours of sleep compared with after two nights of 10 hours ofSleep, suggesting inadequate sleep seems to influence the hormones that regulate satiety and hunger.
